Sandiego fire

FIRE WALL!
Wood burns…not concrete.
Steel softens and bends…not concrete.
ICFs don’t add fuel to a fire. The expanded polystyrene forms are treated with flame retardants. In fact, ICF walls can withstand continuous exposure to fire and temperatures of up to 2,000 degrees F for as long as 4 hours without experiencing structural failure. Compare this to a wood-frame wall that will collapse in an hour or less.
